Abstract: ABSTRACT OF THE DISCLOSURE:           Graft copolymers are prepared by means of a two-step polymerization process, in emulsion:  in the first step,  a vinylaromatic monomer and an acryl or metacryl monomer are grafted on a monomodal polybutadiene latex constituted of particles of diameter comprised within the range of from 800 to 2500 .ANG..  The polymerization/grafting reaction is continued up to a 70-90% conversion,  at which time a further portion of monomodal polybutadiene is added, together with further amounts of monomers,  always in emulsion.    This  process  advantageously  permits  to  pre-pare graft copolymers containing from 10 to 70% of  polybu-tadiene that can be used as such for preparing ABS  resins, without havint to resort to agglomeration techniques.

The fibre matrix is characterised in that its fibres are oriented to a high degree in such a manner that the total matrix fibre length is substan-tially oriented in a main orientation plane, and that membranes are provided between the fibres. It is recom-mended that at least 60%, preferably at least 80% of the total fibre length of the matrix deviate by at most about 20° from the main orientation plane.          The matrix fibres suitably consist of mineral wool, la preferably glass wool, while the membranes consist of a film-forming organic or inorganic material, such as synthetic or natural polymeric materials, glass, metals, ceramics, waxes, fats or oils. The membranes may be impermeable or porous, and active material, such as inorganic catalysts, biocatalysts or adsorbing materials, such as activated carbon and zeolites, may be affixed to or incorporated in the membranes.          The fluid-permeable fibre matrix may be produced by arranging the main orientation plane of the original fibre matrix which has no membranes, substantially vertical, whereupon a film-forming liquid, such as gelatin, is supplied to the upper end of the fibre matrix. With suitable values of the viscosity and the surface tension of the film-forming liquid, mem-branes are formed between the matrix fibres, and these membranes are solidified, for example by polymerisation, evaporation of solvent, or in some other manner. lb

Abstract: ABSTRACT OF THE DISCLOSURE     A process and apparatus for surface coating of workpieces in fluidized beds under atmospheric or slightly higher pressure is disclosed.  The process comprises submerging the workpiece(s) in the fluidized bed, mixing a metal halide with an inert gas to form the fluidizing gas, feeding to the fluidized bed another gas which is capable of reacting with the metal halide in the fluidized bed and coating the workpiece(s).  The workpiece(s) are maintained at a temperature in the range of from 1600°F to 2000°F until it is evenly coated.  The apparatus comprises a saturator vessel for saturating the inert gas with the metal halide and a fluid bed reactor.  There are several advantages that the present invention offers over the prior art, namely, the coating can be performed in a relatively short period of time, 4 to 5 hours and that atmospheric pressure can be used, eliminating the need for a costly vacuum system.

Abstract: ABSTRACT OF THE DISCLOSURE An optical waveguide comprises an out-diffused optical waveguide section, an in-diffused optical waveguide section, and a narrow transition region intimately connecting the out-diffused waveguide section and the in-diffused waveguide section.  This waveguide structure can decrease the level of in-plane scattering caused by surface irregularities, reduce the difficulty of coupling light into and out of the waveguide, the structure can be made to perform as a transverse magnetic mode filter, and increase the intensity of light focussed into the guide beyond the limits imposed by the optical damage resistance of a strictly in-diffused waveguide.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved evaporation cooling module for cooling semiconductor chips bonded onto circuit boards that are immersed in a coolant is disclosed.   A heat exchanger that condenses the evaporated gas of the coolant is immersed in the coolant liquid, and is provided with bubble traps.  The bubble traps are made from a porous metal that collect the bubbles of the evaporated coolant so that they accumulate around the heat exchanger.  As a result, the liquefaction efficiency of the coolant is increased, although the heat exchanger is immersed in the coolant.  The circuit board is provided with a bubble guide which separates the bubbles of coolant from the surface of the circuit board, and guides them to the bubble trap.          Such guided motion of the bubbles causes a local convection current of the coolant, thus further increasing the liquefaction efficiency and improving the uniformity of the temperature distribution over the circuit board.  Since the heat exchanger is placed in the coolant, its liquefaction efficiency does not decrease, as it is separated from the extracted gas which is released from various parts in the module.  Thus, degassing is unnecessary and maintenance is simplified.

Abstract: AEROBIC COMPOSTING APPARATUS     ABSTRACT         The invention concerns an apparatus including an air diffuser device and process useful in the domestic scale aerobic composting of organic wastes.  The air diffuser has within its air admitting opening means to exclude insects, small animal pests and to also exclude waste from entering the air diffuser.  Containers may be employed which have only a single opening admitting access to the contents of the container and the side walls of the container need not have aperatures.  The air diffuser device may be used with a variety of types of containers and particularity with plastic bags.  By using containers which do not have openings to the exterior, except for the opening in which the air diffuser is located and possible small liquid drainage opening, composting may be undertaken with control of pests and flies in regions near residences and without excessive drying of the edges of the compost mass, in a way not previously known.

Abstract: The pump includes a discharge head having a pair of axially spaced end walls. The tank includes a housing in communication with a liquid outlet conduit and forms part of a substantially permanently stationary pipe column which receives clean coolant from the receptor side of a filtration system. By freely suspending the pump by its discharge head in the tank housing of the pipe column, the removal of the pump is facilitated by minimizing the criticality of its mounting connections in the filtration system. The pump is thus mounted for movement between operative and out-of-the-way positions whereby the pump may be readily removed from and reinstalled in the tank without disconnection or connection of pipe fittings within the tank and without aligning the pump with the receptor.
